I have just set up a new x525 quadcopter and cannot get it to respond right, I followed the setup procedure by the letter etc.
It has kk controller black board v5.5 I flashed it with 4.7 firmware to x mode as it was originally in + mode and I wanted to change it,
According to the guide I followed it said to select heli and swash 2 servo 90 but I don't have that option on the dx8 so I just used acro, the guide says when you run the motors and push up on the elevator the back 2 motors (3&4) should speed up but on mine 4&2 speed up and same for aile opposite motors speed up, haven't tried flying it yet as I don't want to risk breaking it until this is sorted out

as soon as i try any throttle it just flips right over to the right, i dont hardly have to move the throttle stick at all,its just so responsive its frightening, lightest touch the motors spin up and the quad just does a full flip to the right and ends upside down.

whats gone wrong ?
i have gone over everything again and again but cant work it out.

That means you must reverse gyro. Watch your xcopter in what direction is flipping over and then reverse that gyro.

5. Revering the gyros
This is how you reverse the compensation direction of the gyros

- Make sure that the flight-controller is turned off
- Turn the Roll pot to the MIN position
- Turn on the transmitter then the flight-controller
- The LED will flash rapidly 3 times and then turn of
- Move the stick for the gyro you want to reverse. (If you want to reverse the roll gyro, move the roll (aileron) stick)
- The LED will flash continually to confirm your choice
- Turn of the flight-controller
- If more gyros needs to be reversed, turn on the flight-controller and repeat the process. If you’ve reversed all the gyros you want, restore the pot to 50%

- Take off the props
- Power the quad, arm it
- Put a little throttle
- Tilt it, the motors going down should speed up to compensate the perturbation
- If the motors going up speed, up then that axis is inverted, and you must reverse it using the procedure listed by er9xuser above
- Do this for pitch and roll, yaw doesn't make it flip so you'll see if that one is inverted on your maiden flight

"- Move the stick for the gyro you want to reverse. (If you want to reverse the roll gyro, move the roll (aileron) stick)"

Any way is good, it's going to reverse it either if you push aileron right or left.

Always check all the reactions with props off, to be sure your escs are plugged the right way, motors turning the right way, and gyros correcting properly, that will save you a lot of times and mone (broken props are $$$)

hi again.
i crashed my x copter the other week and broke the kk board, i have fitted a new board flashed in x config with firmware 4.7 but i am having real difficulty setting it right.
all blades/motors etc are right as it does take off.
the big problem i have is i cant get it to stay straight, it either wants to turn left or right, even with 1 click on the trim will make it go either way but cannot get it to stay straight which makes it impossible to fly
i have tried adjusting the yaw pot but does not make a difference at all.
please any advice would be great before i lose my mind.
i have also re calibrated the esc's
